If you don’t want your animated characters to look fake, you need to work on their muscles.

It’s counterintuitive for an artist who has a character’s external appearance in mind, but it makes for natural-looking movements. An algorithm created by Zhang and colleagues combines the muscle-based model with existing ones based on the movements of skin alone.
